Hi,
I am getting the following error when I try to deserialize an Object with
a Builder and @JsonAnySetter on a field.
Error:
*com.fasterxml.jackson.databind.JsonMappingException: Problem deserializing*
"any" property 'double_score' of class
com.fasterxml.jackson.databind.deser.AdjectiveScore$Builder (expected type:
[simple type, class java.lang.Object]; actual type: java.lang.Double),
problem: object is not an instance of declaring class (through reference
chain:
com.fasterxml.jackson.databind.deser.AdjectiveScore$Builder["double_score"])

The Following is the POJO:
@JsonInclude(Include.NON_NULL)
@JsonDeserialize(builder = AdjectiveScore.Builder.class)
@JsonIgnoreProperties(ignoreUnknown = true)
public class AdjectiveScore {
public static final String ADJECTIVE_ID_STRING = "adjective_id",
ADJECTIVE_TEXT_STRING = "adjective_text";
private final UUID adjectiveId;
private final String adjectiveText;
private final Map<String, String> scores;
private AdjectiveScore(Builder builder) {
this.adjectiveId = builder.adjectiveId;
this.adjectiveText = builder.adjectiveText;
this.scores = builder.scores;
}
@JsonProperty(ADJECTIVE_ID_STRING)
public UUID getAdjectiveId() {
return adjectiveId;
}
@JsonProperty(ADJECTIVE_TEXT_STRING)
public String getAdjectiveText() {
return adjectiveText;
}
public String getScore(String name) {
return scores.get(name);
}
@JsonAnyGetter
public Map<String, String> getScores() {
return scores;
}
@JsonIgnoreProperties(ignoreUnknown = true)
public static class Builder {
private final UUID adjectiveId;
private String adjectiveText;
private final Map<String, String> scores = new HashMap<>();
public Builder(@JsonProperty(ADJECTIVE_ID_STRING) UUID adjectiveId,
@JsonProperty(ADJECTIVE_TEXT_STRING) String
adjectiveText) {
this.adjectiveId = adjectiveId;
this.adjectiveText = adjectiveText;
}
@JsonAnySetter
public void parseUnknownProperties(String name, Object value) {
scores.put(name, (String) value);
}
public Builder score(String scoreName, String value) {
scores.put(scoreName, value);
return this;
}
public AdjectiveScore build() {
return new AdjectiveScore(this);
}
}
}
and the following is the Test to deserialize the JSON to Object:
@Test
public void testBuilder() throws Exception {
String adjectiveText = "great";
Integer intScore = 3;
Double doubleScore = .5;
UUID adjectiveId = UUID.randomUUID();
ObjectMapper JSON_MAPPER = new ObjectMapper();
AdjectiveScore opinion = new AdjectiveScore.Builder(adjectiveId,
adjectiveText)
.score("double_score", doubleScore)
.score("int_score", intScore)
.build();
JSON_MAPPER.readValue(JSON_MAPPER.writeValueAsString(opinion),
AdjectiveScore.class);
}
This test works fine up to the version 2.2.4, AND its starts filing
versions beyond 2.3.0 until recent version 2.8.6.
Please let me know if I am missing something here.
Thanks,
Charan
